IMPROVEMENT IN HEEL-TRIMMING MACHINES.

Specification formingpart of Letters Patent No. 135,745, dated February11, 1873.

To all whom it may concern:

Be it known that I, CHARLES J. Annv, of Boston, in the county of Su'ol'kand State of Massachusetts, have invented a certain new and usefulImprovement in Heel-Trimming Machines, of which the following is laspecifi* cation:

Nature and uObject of the Invention.

-to any desired pattern.

Description of the Drawing.

Figure is an elevation of my machine. Fig. 2 1s a perspective view ofthe same. Fig. 3 is a front elevation of a part of the same.

General Description.

A B O represent the frame to which the several parts of the machine areattached. K Kl K2 is a slide workin g vertically on the upright A. Thisslide K has arms K1 K2, Fig. 3, which serve as housings for the swingingfra-me G1 G2, Fig. 3. G, Figs. l and 2, is a quill extending from theswinging frame G1 G2, and serves as a housing for I the shaft for thecutting or burnishing wheel H. As this wheel H is hung upon the swingingframe G1 G2, which, in its turn, is hung upon the verticallyslidingframe K, it is evident that it is free to move up and down, and alsothat its shaft may be inclined at any angle. G4 is a link rigidlyattached to the swinging frame G1 G2,

.and connected, by a pin, G5, to the slotted arm N, so that the pin G5becomes a second center, about which the swing frame Gl G2 swings as theslidingframe K is moved up and down. I

the wheel H by means of the disk E and pin E, Fig. l. The pin E pressesthrough a slot in the disk, so that, though the relative positions ofthe two disks may change, one will always drive the other. k1 is aweighted lever, having a fulcrum at It, and serves to operate thesliding frame K, and through it and the swinging frame G1 G2 thecutting-wheel H. 7a4 is a footlever which, operating through the link7a3, moves the lever k1. The weight k2 on the lever k1 serves to throwup the cutting-wheel H when not in use. The cutting action of the wheelH is limited and regulated by the moving guidel Z1 l2, Fig. 3. Thisguide has a rack on its under side which engages with the pinion L, Fig.3. The slide K, the motion of which governs the cutting action of thewheel H, is provided with a pin, K3, which rests, when the machine is inaction, upon the sliding guide l l1 l2, and, as the guide l l1 l2 ismoved by the action of the heel-piece M, it will limit the motion of thecutter a-nd cause it to cut the heel into the proper shape, the exactshape being govern ed by the guide lll l2. The angle of the edge of theheel is automat ically regulated by themotion of the arm G1 G? as theshoe revolves.

I claim as my inventionl. The combination of the cutter H, the arm G1G2, and the sliding frame K, substantially as described, and for thepurpose set forth.

2. In a heel-trimming machine, the sliding guide Z Z1 l2, operating, incombina-tion with the cutter H, substantially as described, and for thepurpose set forth.
